A spring compressor having a vertical post with a movable spring mount on the middle part of the post and a fixed spring mount on the upper part of the post. A self-contained, hydraulic jack is mounted between the movable spring mount and the lower part of the post or a base supporting the post. The jack is operable to move the the movable spring mount up toward the fixed spring mount to compress a spring between them. The fixed spring mount can be adjustably mounted on the upper part of the post. Each spring mount has a pair of support arms. There is a spring engaging hook at the end of each arm. The arms on each mount are movable toward or away from each other and are also swingable in a vertical plane so that they can be easily mounted on a spring. Adjustable stops are also provided for limiting upward movement of the arms on the fixed spring mount and for limiting downward movement of the arms on the movable spring mount.
Compresseur de ressort composé d'un montant comprenant, sur sa partie centrale, une monture de ressort mobile et, sur sa partie supérieure, une monture de ressort fixe. Un vérin hydraulique autonome est installé entre la monture mobile et la partie inférieure du montant ou d'une base supportant le montant. Lorsqu'il est actionné, le vérin relève la monture mobile vers la monture fixe pour comprimer le ressort disposé entre les deux montures. Il est possible de régler la position de la monture fixe sur la partie supérieure du montant. Chacune des montures de ressort comporte une paire de bras de support, chaque bras portant à son extrémité un crochet pour retenir le ressort. Les bras de chacune des montures peuvent être approchés ou éloignés les uns des autres et peuvent basculer à la verticale de sorte à en faciliter la pose sur le ressort. Le dispositif comporte également des butées réglables qui limitent le mouvement ascendant des bras sur la monture fixe ainsi que le mouvement descendant des bras sur la monture mobile.
